Application iled March 27, 1905. Serial No. 252,333.

To all whom it may concern:

Be it known that I, FRANK PARIZEK, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certainv new and useful Improvements in Gasolene-Torches, of which the following is a specication.

This invention relates to a gasolene-torch for plumbers or painters use; and the object of the invention is to improve the construction and operation of the torch as a whole and to the several parts thereof.

The invention relates more particularly to the swivel-mounting for the burner by which the burner is enabled to be turned regardless of the position of the tank, to the method of supporting and positioning the burner, to the construction and location of the drip-pan, and the construction of the valve for controlling the liow of compressed air from the pump.

In the drawings illustrating the invention, Figure 1 is a sectional elevation of the entire torch; Fig. 2, an enlarged detail of the supp ply-pipe for gasolene; and Fig. 3, a modification thereof The torch as a whole consists of a cylindrical tank 1, provided with a plug 2 for supplying gasolene thereto, and said tank has at one side a pump 3, consisting of a cylinder 4, lhaving therein a piston 5, operated by means of a rod 6, and handle 7, which rod passes through a cap 8, which closes the upper end of the pump-cylinder. Thelower open end of the cylinder is entered into a socket 9, which is formed integral with a valve-casing 10, diagonally disposed with respect to the pumpcylinder, and said valve-casing has leading therefrom a tube 11, which extends obliquely with respect to the valve-casing and at right angles to the pump-cylinder. The tube is provided at its end with a screw-threaded nipple 12 of less diameter than the tube, which nipple is entered into the wall of the gasolene-tank, and the tube is provided with a shoulder 13, which abuts against the outer face of the wall of the tank and coacts with a bushing 14 for clamping the metal of the tank between the bushing and the shoulder. The valve-casing is provided with a lower enlarged valve-chamber 15 and an upper enlarged chamber 16, separated from one another by means of an annular flange 17, leaving a contracted port between the two valve-chambers. The lower valve-chamber communicates with the socket 9 through a port 18, and into the end of the lower valve-chamber is screw-threaded a regulating-valve 19, terminating at its inner end in a reduced valvestem 20, which is adapted to loosely enter the contracted port between the upper and lower valve-chambers, leaving a shoulder 21, adapted to seat against the annular iiange between the two chambers when the adjustable valve is screwed up to its limit. In the upper charnber is located a check valve 22, having a stem 23 encircled by a coil-spring 24, which coil-spring at one end abu ts against the checkvalve and at the other end abuts against a set-screw 25. The upper chamber communi- 'cates with a duet 26 in the tube l1, which duct communicates with a pressure-pipe 27 on the interior of the tank, terminating near the top thereof.

The tube 11 and parts attached thereto serve as a support for the lower end of the pumpcylinder, and the upper end of the pump-cylinder is held by'means of an arm 28, provided on its end with a screw-threaded stud 29, a shoulder 39, and bushing 31 for securing the arm to the wall of the cylinder near its top.

A gasolene-pipe 32 is entered into the tank near one side and extends to near the bottom of the tank, passing through a collar 33, having an enlarged stufng-box 34, leaving a shoulder 35, and the gasolene-pipe has in its exterior a groove 36 on a line with the shoulder 35, into which groove is entered a split ring 37, which bears against the shoulder. The stuffing-box has entered thereinto a gland 37, adapted to compress a packing 38, and the gland at its upper end terminates in an enlarged drip-pan 39, located exterior of and slightly above the tank. The gasolene-pipe, as shown in Fig. 1, is provided above the drippan with a loop 40 and terminates in a rearwardly-extending section 41, screw-threaded at its end. The loop 40 surrounds a cylindrical burner 42, open at its discharge end 43 and conical at its intake end 44, and said burner rests upon and is supported by the rearwardly-extending terminal end 41 of the gasolene-pipe. The burner is secured to the pipe by means of lugs 45 and 46, which are preferably cast around the gasolene-pipe for firmly and intimately uniting the burner thereto.

with; but in other respects the arrangement is the same as that shown in Fig. 1.` To the end 41 of the gasolene-pipe is screw-threaded a regulating-valve 47, provided with an obliquely-extending tubular arm 48, communieating with a valve-chamber 49, which valve- As shown in Fig. 3, the loop is dispensed IIC chamber terminates at its discharge end in a tapered nozzle 50in line with the conical end 44 of the burner. The discharge from the nozzle 50 is regulated by means of au adjustable needle-valve 51, entered through a stuffing-box 52 and terminating in ahandle 53 for regulating the position of the needle-valve, which is provided with screw-threads 54 for permitting its adjustment. The burner is provided with perforations 55 for the purpose of admitting air to its interior.

In order to prevent the admission of dirt or sediment into the bu rner-valve, a screen 57 is located in the pipe 41, which serves to arrest the passage of any foreign substance into the valve, and a perforation 56 for the escape of liquid gosolene from the burner.

In operation the gasolene is poured into the tank and the valve 19 screwed back sufficient-ly to unseat, after which the pump is operated and the compressed air generated in the pump is driven through the valve, raising the checkvalve with each downward stroke of the pump and storing up compressed air in the top of the gasolene-tank. After sufiicient pressure has been stored up the burner-valve can be opened and the `gasolene under pressure will be discharged in a fine stream or spray into the burner and ignited. The gasolene-pipe serves as a pivotal mounting for the burner, allowing the same to be readily turned while the tank remains stationary, which is a feature of great advantage in that it allows the flame from the torch to be directed in a manner which would be impossible if the burner were stationary. The construction of the drippan is such that its end serves as a gland for compressing the packing in the stuffing-box,

valve-casing and pump-socket to be formed from a single casting, which strengthens the construction and enables the valve-casing and parts attached thereto to serve as a strong and rigid support for the pump-cylinder, which cylinder serves as a handle for the manipulation of the torch as a whole.

The method of forming the gasolene pipe and coil out of one continuous tube does away with all screw-joints and at the same time provides asmooth continuous passage-way, which prevents the accumulation of sediment or dirt. As ordinarily constructed the gasolene-supply pipe has been provided with loops or seams which provided angles or corners for the collection of dirt and materially weakened the construction and increased the probability of leakage.

What I regard as new, and desire to secure by Letters Patent, is-

l. In a gasolene-torch, the combination of a gasolene-tank, a pump adapted vto create pressure in the tank, a stufling-box in the top of the tank, a drip-pan provided with a tubular stem screw-threaded into the stuiing-box, a packing within the stufIing-box, a gasolenepipe entered through the drip-pan and stuifing-box and revolubly held thereby, a loop on the end of the gasolene-pipe terminating in a rearwardly-extending section of pipe, a needle-valve secured to the end of the rearwardlyextending section, and a burner surrounded and supported by the loop in line with the valve,'-substantially as described.

2. In a gasolene-torch, the combination of a gasolene-tank, a pump for supplying pressure thereto, a stuffing-box in the top of the tank, a drip-pan provided with a screw-threaded stem entered into the stuing-box, a packing adapted to be compressed by the stem, a gasolene-pipe passing through the drip-pan and stuiing-box and provided with an exterior groove or channel, a ring entered into the groove or channel and lying within the stuffing-bornand a valve-controlled burner carried by the gasolene-pipe, substantially as described.
